PING, PONG, BOOM AND TOOT Ping plays the strings which grow vertically out of his head. He can pluck them like a banjo, play them like a fiddle, or strum them like a guitar. Pong provides keyboard sounds by playing his finely-tuned teeth, which are capable of producing, as required, such different sounds as piano, organ or xylophone. Boom provides a wide range of drumbeat sounds by pounding his massive chest with drumsticks. Toot plays his nose flute in a variety of ways which can make it sound like a saxophone, a flute, a trumpet or a clarinet.
